Network Changes

by Max B

Daniel and I made a few changes to the network configuration last night. We had noticed that our connection was much slower than it should've been and found a couple areas where we thought we could make improvements: tl;dr: We fixed some janky old wiring, replaced a server that was bloated, and added a wireless AP. There's bunches more to do and to document! Text wall incoming... - We moved the modem from the backspace area to the sudoroom server rack platform. We were able to keep the crazy phone + ethernet situation, but with many many fewer crazy wire splits and adapters hanging off of ethernet cables. It's a lot cleaner now - We moved the gateway from the middle of the red servers to the dell poweredge server on the top. We suspected that the fancy zentyal software on the red server was a little bloated/mis-configured. Getting an ethernet connection directly from the modem was providing 30Mb/s, but getting a connection anywhere after the zentyal server it was dropping to 10Mb/s. We installed Ubuntu Server 14.04 LTS and set up some basic networking rules (read - no security per se). It's only got 2 ethernet ports, so it acts as a dhcp client on one interface and gets internet in from the modem and then does NATing and provides a dhcp server on the other side. There were a number of devices in sudoroom that have fixed 192.168.42.0/24 network ip addresses, so I setup the server to provide addresses on that range. - We added a wireless AP repeater to the sudoroom area. It's on channel 1 which doesn't overlap much. There should be three ssids in sudoroom with strong signal "sudoroom2.4ghz" "sudoroom5ghz", and "sudoroom24g2" (or something like that last one...). Daniel ran some cable from the server racks to the ball room and I was going to put a picostation there, but I was having trouble finding a picostation that would flash. So the wiring is all ready for an AP, but we just need to get a working picostation over there. Which leaves us with some notes and some todos: - It looked like a number of devices were all trying to provide dhcp servers on the 192.168.42.0/24 network. This doesn't seem like a particularly good idea to me. I don't see any reason we can't just do one of two things when we add a router: 1. Let it provide DHCP, but on a different subnet, with NAT or 2. Set it up to bridge connections to the LAN where the rack server will provide dhcp. - The server can use a bunch of configuration. I really don't know how security policy can/should work at sudoroom. It seems a little silly to have a complex firewall on a machine that's accessible to the public and has a sudo username/password written on top of it. - Need to get a picostation in the ballroom (maybe peoplesopen node once we feel confident we can guarantee that the tunnel to the exit node will stay up?) - We could probably use one more AP in sudoroom proper. We're currently using channels 1 and 6 I believe for the two APs. There are ~3 non-overlapping 2.4Ghz channels, so we might as well make full use of the spectrum and add a channel 11 AP - Would be nice to go around and make sure that no one else is providing DHCP on the 192.168.42.0/24 subnet. There were even a couple instances where I think I realized that we were inadvertently running an extra DHCP server. That visio AP in sudoroom had been plugged into the switch on the LAN side. It was a cute trick to keep everyone on the same subnet and if the visio had been smarter, it would've gone into proper bridged mode, but I'm not sure that was the case. - Figure out a better(?) IP allocation scheme. Right now the ubuntu server is providing 192.168.42.0/24 addresses and the visio router is NATing and providing 192.168.6.0/24 addresses (don't ask me why I picked that - it was really late/early). I think that will mean that folks connected to the visio will be able to access services on the 192.68.42.0/24 LAN, but not the other way around. - Document! I'm super guilty of not doing a good job of this, but Daniel and I were scrambling to get stuff in place and working. I think every router and host with a fixed ip address (or more) should get labelled with those addresses. I need to document this process on the wiki (this email was partially a preface to that). And, I think we should try to either provide a network diagram or maybe even a live monitor for folks to see what the hell is going on. It'd be pretty snazzy to be able to go to a web site somewhere and see the network topology/connected hosts. Either that or we could just use crayons..... Ok that's all I got for now, Max

Tor local area network anonymizer... maybe for Sudo?

Error messages for the 15 users with "failing credit card on file": - (10) This transaction was declined by the card issuer. Customer please call bank. - (4) This card has been invalidated. - (1) Invalid Account Number "declined by card issuer" means the issuer thinks the transaction might be fraud (for any number of reasons). More information hopefully forthcoming as well... https://github.com/gittip/www.gittip.com/issues/2666#issuecomment-52997368 // Matt
